Title: A build log of RCTIMER Quad kit Post by: santhosh-r on March 14, 2014, 07:27:26 PM Hello friends,
I was astonished by these multicopters for about an year or so.I always wanted to build a quad.After months of research and proper financing at last I placed an order with RC Timer for the 450 V2 kit with integrated PCB on 11 MARCH 2014 . To my first surprise they had sent it thru DHL express ( too much for a free shipping).It left their china warehouse on 12 March 2014. I was eagerly tracking it on track-trace.com . since it was sent thru courier I was fearing that there might be a hefty customs on the parcel. The parcel reached me today evening 6:00 pm and another surprise there was no customs at all.. For the order - Free DHL express shipping + No customs + Fast delivery withing 3 days.... ;D Within an hour of arrival I was able to completely assemble the kit. The pictures will follow this post. Title: Re: A build log of RCTIMER Quad kit Post by: santhosh-r on March 14, 2014, 07:29:16 PM I already have a NanoWii board and 3S 2200mAh 20C Turnigy lipo.
I am waiting for my bullet connectors to arrive , as only the motors had bullet connectors. Title: Re: A build log of RCTIMER Quad kit Post by: santhosh-r on March 14, 2014, 08:10:21 PM Guys can I submit this for RC India sweeptake ??
I didn't take photo with a news paper ! Title: Re: A build log of RCTIMER Quad kit Post by: anwar on March 14, 2014, 09:24:56 PM If you post the tracking number of the shipment by which we can confirm the build date, we will sure add it.
Title: Re: A build log of RCTIMER Quad kit Post by: santhosh-r on March 14, 2014, 11:12:02 PM Ok anwar sir.
The tracking no. is 2977109693 via DHL express. http://www.dhl.com/content/g0/en/express/tracking.shtml?brand=DHL&AWB=2977109693&commit=Track%21 (http://www.dhl.com/content/g0/en/express/tracking.shtml?brand=DHL&AWB=2977109693&commit=Track%21) Title: Re: A build log of RCTIMER Quad kit Post by: Shyam Hembram on March 14, 2014, 11:38:57 PM hii,Santosh does rc timer offers free shipping in evry product.
Title: Re: A build log of RCTIMER Quad kit Post by: santhosh-r on March 15, 2014, 08:01:30 PM Not every, but almost 90% of them.
Title: Re: A build log of RCTIMER Quad kit Post by: Shyam Hembram on March 16, 2014, 12:22:37 AM Santosh you did your payment through PayPal or direct via atm card???
Title: Re: A build log of RCTIMER Quad kit Post by: santhosh-r on March 16, 2014, 09:37:01 AM Payment was done through Paypal.
Title: Re: A build log of RCTIMER Quad kit Post by: ayu135 on March 19, 2014, 10:26:28 PM I too ordered stuff via rctimer, but i didnt get a free shipping option. I had to pay $20 for shipping. It was sent via DHL and no customs for me either. I had ordered stuff around $200 in value. I ordered on 14th and recieved it today. Great service.

Title: Re: A build log of RCTIMER Quad kit Post by: santhosh-r on March 20, 2014, 06:01:39 AM I have a problem now :help:.
Finished soldering bullet connectors ,Nanowii board, motor directions ,fixing everything. I calibrated the esc by , 1.power up the board alone via USB 2.Arm the board + full throttle 3.Power up the ESC 4.Wait for throttle calibration tones 5.Bring the throttle down and disarm I tried to power the quad and the results are, When I give throttle ,the motor respond only after 40% throttle even though it was calibrated. The throttle response is very fast so that it goes up like a rocket when it starts to lift. The prop is a 10x4.5 and 30A RCT SimonK ESC with Nanowii board - F/W Multiwii 2.2 No changes to the default PID values has been made. The video of the test flight is, https://www.youtube.com/watch?v=X5og_aebvSY (https://www.youtube.com/watch?v=X5og_aebvSY) Title: Re: A build log of RCTIMER Quad kit Post by: Rahulvyas on March 20, 2014, 07:49:04 AM Check your radio Stick calibration..
Title: Re: A build log of RCTIMER Quad kit Post by: santhosh-r on April 14, 2014, 11:17:12 PM Had a good maiden flight !
Now PID tuning in process.... https://www.youtube.com/watch?v=2R3bESZcfFo (https://www.youtube.com/watch?v=2R3bESZcfFo) Title: Re: A build log of RCTIMER Quad kit Post by: Swapnil on April 15, 2014, 09:18:14 AM Good maiden! :thumbsup:
Title: Re: A build log of RCTIMER Quad kit Post by: satyagupta on April 15, 2014, 10:20:07 AM Test flight inside home ??? ??? that too on your hand :o :o :o :o :o
Not good job to do bro, just take lot of care. These things are damn dangerous, they can slash through your skins like a sharp knife :-\ :-\ Title: Re: A build log of RCTIMER Quad kit Post by: K K Iyer on April 15, 2014, 03:40:15 PM Second that advice.
Title: Re: A build log of RCTIMER Quad kit Post by: santhosh-r on April 15, 2014, 04:42:17 PM My fear is that , outside if I overcorrect or any overshoot in PID can result in loss of my quad and also the throttle , if I give more then the quad may get out of control!
Title: Re: A build log of RCTIMER Quad kit Post by: Swapnil on April 15, 2014, 05:14:59 PM You can always tether the quad using strings to something heavy when you are testing indoors (like 'Dharmik' did... he used a tub I think...).
Title: Re: A build log of RCTIMER Quad kit Post by: maahinberi on April 15, 2014, 07:19:17 PM More chance to damage quad indoors than outdoors. Fly in a field with grass, and you will walk away without damage from most crashes.
Title: Re: A build log of RCTIMER Quad kit Post by: santhosh-r on April 16, 2014, 05:10:55 AM BTW , one of the motors is itself not balanced .This is causing more vibrations and the props that came with the kit are worst balanced !
Title: Re: A build log of RCTIMER Quad kit Post by: santhosh-r on May 03, 2014, 11:36:03 AM Ordered landing skids for my quad and attached them.
To reduce vibrations picked up by Nanowii I decreased the LPF value to 42Hz.Now the quad is much stable but I could see the vibrations in the motor with my naked eye. Title: Re: A build log of RCTIMER Quad kit Post by: ved on May 03, 2014, 09:37:02 PM Try using some tape on the propellers to minimise the vibrations. Also check the prop adapters.
Title: Re: Re: A build log of RCTIMER Quad kit Post by: santhosh-r on May 04, 2014, 10:25:49 AM The prop adapters are worst balanced!
Title: Re: A build log of RCTIMER Quad kit Post by: santhosh-r on May 13, 2014, 10:09:38 PM Found the best way to eliminate vibration - don't use the prop adapters instead place the prop directly over the motor and attach it using cable tie.
It works the best ;D ! -very minimal vibration as if it doesn't have a prop and the motor is running w/o prop. |
